[mythtv] dvb data timeout problem

With current cvs, my picture will often not tune until the 15 second 
"Could not read data" timeout is crossed.
Happens on two backends, one dvb-t and one dvb-c
Autopid runs OK, but then nothing happens until the timeout, then 
autopid runs again and the picture appears.
It's odd, cos it gets the same pids each time.
I notice I don't get this line on the failed tune:
